Sure, here are the steps on how to set an enum from user input in Python:

1. Create a variable to store the enum value.
2. Create a loop to get user input.
3. Use the try-except block to check if the user input is a valid enum value.
4. If the user input is a valid enum value, then set the enum value to the variable.
5. Otherwise, print an error message.

Here is an example of how to set an enum from user input in Python:

Python

enum MyEnum(str):
  Value1 = "VALUE1"
  Value2 = "VALUE2"
  Value3 = "VALUE3"

# Create a variable to store the enum value.
myEnum = None

# Create a loop to get user input.
while myEnum is None:
  print("Enter an enum value:")
  userInput = input()

  # Use the try-except block to check if the user input is a valid enum value.
  try:
    myEnum = MyEnum(userInput)
  except ValueError:
    print("The value is not a valid enum value.")

# Print the enum value.
print("The enum value is:", myEnum)

In this example, the MyEnum enum has three values: Value1, Value2, and Value3. The myEnum variable is a variable that stores the enum value. The while loop gets user input until the user enters a valid enum value. The try-except block checks if the user input is a valid enum value. If the user input is a valid enum value, then the myEnum variable is set to the user input. Otherwise, an error message is printed.
